OIL BURNER.

Application filed March 24, 1922. Serial No. 546,263.

To all whom it may cancer-n:

Be it known that we, BERNARD A. GEURINK and LOUIS H. Gnnnrrm, citizens of the United States, and residents of East Cleveland, county of Cuyahoga, State of Ohio, have jointly invented a new and useful Improvement in Oil Burners, of which the following is aspecification, the principle of the invention being herein explained and the best mode in Which we have contemplated applying that principle so as to distinguish it from other inventions,

The present invention relates to an oil burner in which provision is made for pre heating and vaporizing the fuel and then passing it through a superheater, at which time, it is'mixed with air to form the combustible mixture. In particular, the invention relates to the construction of the heating pipes and burner, whereby the pie-heating and superheating is obtained. To .the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing:

Fig. 1 is a top plan view of one form of burner; Fig. 2 is a second view on the line 22 of Fig.1; Fig. 3 is a section on the line 3-3 of Fig. 1; Fig. 4 is an elevational view in a modified form of burner adapted for use with radiant burners; Fig. 5 is a top plan view of the device shown in a without the enclosed casing; and Fig. 6 is asectional view on the line 6-6 of Fi The form of burner shown in Figs. 3 consists of a burner plate comprising a hollow burner ring or pipe 1, with slots or burner openings 2 at the top for the coin bustible gas, and this ring is provided across the center with a substantially rectangular chamber 3 which is depressed slightly below the level of the ring, and this chamber, as best shown in Fig. 2, is provided with a dependingpocket 4 at the rear. Around the righthand half, as shown in Fig. l, the burner is provided with a downwardly deg. 5. 1 to pending flange 5 of approximately the same depth as the pocket, and on the other side the burner ring is provided with a semicircular rectangular tube 6 curved to conform to the burner ringand in alignment underneath the same. This tube 6 is provided with a continuous wick cup 7 extending outside of the tube and beyond the edge of the tube and burner ring. This tube at the back of the burner extends into the depending pocket 4 and communicates therewith. Above this wick cup is mounted a fuel heating tube 8 which extends approximately onehalf way around the burner and is mounted at the back in a bracket 9 which is secured by means of ascrew 13 or the like, to a boss 10 formed on the burner casting, and at the front end the tube communicates with a valve housing member 11 to which it is attached by means of a screw 12. Above this fuel heating tube 8 is mounted a second larger heating tube 14 which is also carried in the valve casing at the front, and this larger tube is provided with a bulging portion 15 at the rear which communicates with the central chamber of the burner above the pocket by means of an aperture 16 in the end of the burner ring. At the front end of the burner this second heating tube is provided with an air inlet conduit 17.

In the valve casing at the front of the burner are mounted two valves 18 and 19, one of which seats in the valve seat 20 which controls the flow of the fuel. vapor from the lower or fuel heating tube 8 into the passage-way through the valve chamber and the other valve controls the flow of such gas into the upper large tube as best shown in Fig. 3.

At the right side of the burner there is mounted a valve casing 21 to which is co ,nected the fuel supply pipe 22 and this valve casing is provided with a hand controlled valve 23 which controls the flow of oil through the casing to the fuel outlet pipe 24 which communicates with the fuel heating tube 8 at the back of the burner. The oil which enters this tube will be heated and will pass around and through the fuel heating tube to the valve casing at the front of the burner and then up and into the second or air heating tube where it will be supe heated and also miX'ecl with air from which which is partially filled with shredded as it will iiow into the burner casting at the back, and thus around the burner ring and through the rectangular transverse tube. A certain portion of the combustible gas will flow into the pocket at the rear of the burner and then out through the rectangular tube 6 which is shown in Fig. 2 and is provided with a series of burner holes or apertures in the outer vertical face of the tube and the combustible mixture will be ignited at the outside of this tube above'the wick cup and thus directly below the oil heating tube and the air heating or super-heating tube.

In originally starting the burner, the wick cup which is directly below the two heating tubes and which is partially filled with shredded asbestos 26 or the like to form a wick, will be partiallyfilled with alcohol or similar fuel which will be lighted in order to originally heat up the fuel heating tube 8 and the air heating or super-heating tube 14. As soon as these two tubes 8' and id have become sufiiciently heated, fuel can be admitted to tube 8 by opening the. valve 13 and then oil will become vaporized, and by opening the valves at the front of the casing, the vaporized oil will pass to the superheating tube 14 where it will be mixed with air and super-heated before passing to the burner proper.

In Figs. 4 to 6 we have shown a modified form of burner construction which par- .ticularly adaptedto he used with a socalled radiant heater which, as shown, comprises; a hooded stand 30 carrying the entire burner mechanism and also a series of radiant heaters 31 of fire clay or the like which are mounted directly above small individual burners 35, having a series of apertures or slots 32. In this form the burner consists of a straight burner pipe ofgeneral rectangular cross section but here shown as being slightly narrower atthe base than at the top. and this burner pipe is provided at oneside with a cupshaped flange 3% extending the entire length of the pipe and acting as the wick cup bestow 2-6 or other suitable wick material. This burner pipe is provided with a series of upwardly extending burner tubes 35 which are the slots or apertures to fur nish outlet for the fuel and the radiant members fit snugly over these burner tubes as best shown in Fig. 6. V

I In this construction there an oil sup ply pipe 3'? which communicates with '21 single control valve 38 mounted on a bracket 39 on the heater stand 30, this valve in turn communicating with a fuel. heating tube 40 extending longitudinally along the side of the burner pipe 33 and above the wickcup 34, and this oil heater pipe car rise at the back a coupling 41 also connected to an air heating tube or super-heating er pipe 33 being here provided with a series of small apertures 45 in the side adjacent the wick cup so that gas may be ignited to furnish a heating flame directly under the fuel heating tube to and the air or superheating tube 4:2. The fuel oil is supplied to the fuel heating tube 40 where it is raporized and it then passes into the air heat ing tube 42 where it is mixed with air and superheated before passing into the burner pipe from which it passes to the burner tube slots or apertures to heat the radiant members and it also passes out of the small apertures 45 to heat the two tubes. 1

I The present burner is very satisfactory from the standpoint of burning without odor, and thus can be used as an open burn er, the first form illustrating a typical type of burner such as would be employed for stoves, water heaters or the like. while the second form shows the present device in combination withthe radiant heater such as is commonly used for heating with fuel gas. The burner is easy to start as the long wick cup allows the entire fuel heating: tube to be quickly heated to the desired temperature and then as soon as oil is admitted to this tube it will become thoroughly vaporized before passing to the super-heating tube where it is mixed with air and then super-heated to form a combustible 'mixture before passing into the burner pipes proper. The entire burner is compact and easily controlled and the heating action is such that perfect vaporization and combustion is obtained. The parts are easily formed and readily assembled, the burner whether in ring form or straight, being preferably a casting and the heating tubes can be readily attached hereto by using standard fittings which decreases the cost of manufacture and assembly and allows present burner to be economically manufactured. 1

Other modes of applying t. p of our invention may be empl l i of the one explained. change being as regal provided the means stated by any of the made the mecha uisin herein disclosed.
